The tubular shaft has an inner diameter of 15 mm. Determine to the nearest millimeter its minimum outer diameter if it is subjected to the gear loading. The bearings at A and B exert force components only in the y and z directions on the shaft. Use an allowable shear stress of τallow = 70 MPa , and base the design on the maximum shear-stress theory of failure.
The speed of the ball relative to the quarterback is 60 ft/sec. What is the absolute speed of the ball? Treat the problem as two-dimensional.
A truck is traveling down a road with a 3-percent grade at a speed of 55 mi/h when the brakes are applied. Knowing the coefficients of friction between the load and the flatbed trailer (us= 0.40) and (uk= 0.35)
The three blocks shown move move with constant velocities. Find the velocity of each block, knowing that the relative velocity of A with respect to C is 300 mm/s upward and that the relative velocity of B with respect to A is 200 mm/s downward.
For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant?
A contractor has both a 3-cy and a 5-cy shovel in the equipment fleet. Select the minimum-size shovel that will excavate 400,000 bcy of common earth in a minimum of 130 working days of 8 hr each.
Assuming isentropic flow, determine the pressure and temperature of air at a location where the air velocity equals the speed of sound. What is the ratio of the area at this location to the entrance area?
Two smooth circular cylinders of weight w=500N and radius r=200mm are connected at their centres by a string AB of length 600mm and rest upon a horizontal plane.
how long does it take for the truck to move 4 m up the incline?
The velocity of flow toward the sphere along the longitudinal axis is found to be u = - U0 (I - r~/_xl), where r0 is the radius of the sphere and x the distance from its center.
